This episode has been difficult to write. In fact, the last several have been difficult, and it all comes down to issues of time. Not space time flexing due to gravitational pull, and issues of whether a minute for Alfred in Wessex was the same as a minute for someone climbing the alps. Just good old fashioned questions of timing.
What goes first? When does it happen? What happens next and when?
The problem is that history, at its root, is a story, and a story generally needs a sequence of events. I mean, sure, some storytellers like William S Burroughs have completely cast off the idea of a sequence to great effect. But in general, to tell a story that people can understand, A needs to be followed by B which needs to be followed by C.
